The Open Group has been the custodian of the specification for the UNIX system and the trademark since 1993. The effort that led to
this transfer was the catalyst for all vendors to make their systems conform to this single definition, a goal that had been elusive in
previous harmonization efforts. Today all the major vendors support the Single UNIX Specification and have registered product.

ABOUT THE OPEN GROUP

The Open Group is committed to delivering greater business
efficiency by bringing together buyers and suppliers of information systems to lower the
cost and risks associated with integrating new technology across the enterprise. The
Open Group, a vender and technology-neutral consortium, ensures that multi-vendor
information technology matches the demands and needs of customers. This is achieved
through the development and deployment of frameworks, polices, best practices and
standards in pursuit of the groups IT DialTone vision --- the concept of making all
technology as open and accessible as using a telephone.

By leveraging the expertise of its sponsors  Compaq
(NSYE: CPQ), Fujitsu, HP (NYSE: HWP), Hitachi (TSE:6501), IBM (NYSE: IBM), NCR (NYSE:
NCR), Siemens, Sun (NASDAQ: SUNW) - and other members comprising leading software
companies, Fortune 500 users and government departments, The Open Group is well on its way
to achieving the DialTone vision. Embracing the maxim: "we can do so much more
together than alone", The Open Group is helping its members to stay ahead in the race
to use technology to gain competitive advantage. Additional information about The
Open Group is available at the consortiums web site at http://www.opengroup.org.
